Condition Analysis
AI-powered assessment using site data and 14-day weather history
Back Bowden Doors is currently unsafe to climb. The crag has experienced a prolonged wet period with over 54mm of rain in the last 28 days, including significant rainfall on June 1–4 (35.3mm) and repeated light-to-moderate showers since, with the most recent rain falling today (1.4mm) and yesterday (0.1mm); the sheltered valley position and high humidity (~79% average over the last week) mean the porous Fell Sandstone will be thoroughly saturated internally despite any surface drying.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- Back Bowden Doors sits in a sheltered valley with a wooded section that dramatically slows air circulation and drying compared to the exposed hilltop of Bowden Doors proper — expect drying to take significantly longer than general guidelines suggest.
- The powerful roof problems and overhanging features are known to weep from above after rain, with seepage persisting for days as water drains through the rock from the top of the crag.
- The west-facing aspect only receives afternoon and evening sun, which in combination with the sheltered position provides limited solar drying — especially in overcast conditions like those forecast this week.
- Seasonal bird nesting restrictions may be in effect (typically March–August); check the BMC RAD for current restrictions before visiting.
Warnings
3
- Climbing on saturated Fell Sandstone causes permanent, irreversible damage to holds and routes — the rock may appear surface-dry while retaining dangerous levels of internal moisture.
- The prolonged wet period means the rock has been repeatedly saturated over weeks; internal drying will take far longer than the standard 48–72 hour guideline.
- Roof problems and overhangs at this crag are known to weep from above after rain — check for active seepage even if the climbing surface appears dry.
Reasoning
The rock is almost certainly saturated internally: 54.3mm of rain over the past 28 days with only brief dry spells, culminating in 6.5mm on June 11 followed by just 3 fully dry days before today's 1.4mm, means the Fell Sandstone has had no opportunity to dry out meaningfully.
The sheltered valley position, high average humidity (79%), and west-facing aspect with limited direct sun mean drying has been extremely slow; even the 3 dry days (June 12–14) with moderate westerly winds were insufficient to clear accumulated moisture from such a prolonged wet period.
With the rock likely at high internal saturation from weeks of repeated wetting, compressive strength could be reduced by 30%+ (Bell, 1978), making hold breakage a serious risk — especially on the iron-oxide-cemented small holds characteristic of Fell Sandstone.
Early summer conditions should normally favour drying, but this June has been exceptionally unsettled with well-above-average rainfall; the forecast shows continued showers through at least June 21, preventing any meaningful drying window.

54.3mm over 28 days with repeated wetting events means deep internal saturation of this porous sandstone, far beyond what surface appearance would suggest.
Rain fell today (1.4mm) following only a brief 3-day dry spell after the last significant rain on June 11, providing no adequate drying window.
Average humidity of 79% over the past week, with today reaching 90%, severely limits evaporation from the rock surface.
The sheltered, partly wooded valley setting drastically reduces wind exposure at the rock face, removing one of the most effective drying mechanisms.
The 5-day forecast shows rain on every day (totalling ~11.2mm), meaning no drying window is available in the coming week.
Temperatures around 13–19°C are adequate for evaporation in principle, but this benefit is overwhelmed by the persistent moisture and humidity.
SW winds of 20–39 km/h have been present on some days and offer some surface drying potential, though the sheltered position limits their reach to the rock face.
Recommendations
3
- Do not climb at Back Bowden Doors until there have been at least 3–4 consecutive fully dry days with humidity below 75% and moderate wind — given the cumulative saturation, even this minimum may be insufficient.
- If visiting the Northumberland area, check whether the more exposed hilltop crag at Bowden Doors proper is in better condition, though it too will need significant drying time.
- Monitor the BMC RAD and local forums for condition updates and confirm whether seasonal bird nesting restrictions are in effect before planning a visit.

Back Bowden Doors has received over 54mm of rain in the past 28 days with repeated wetting events, and the last significant rain (6.5mm) fell just 4 days ago on June 11th, followed by only 3 dry days before today's renewed rain. The sheltered valley position, high humidity, and ongoing forecast rain mean the porous Fell Sandstone will remain internally saturated and unsafe to climb.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley position and wooded surroundings significantly reduce airflow at the rock face, meaning the site dries far slower than the exposed hilltop at Bowden Doors proper — add at least 24–48 hours to any normal drying estimate.
- The powerful roof problems and overhanging sections are known to weep from above after rain as water percolates through the caprock; even if vertical faces appear dry, seepage lines can persist for days in this setting.
- With 54mm of cumulative rainfall over 28 days and only brief dry windows between repeated wetting events, the sandstone has had no opportunity to fully dry internally — the deep pore network will be heavily saturated.
- Bird nesting restrictions may be in effect during June; check the BMC RAD for current seasonal closures before visiting.
Warnings
3
- The Fell Sandstone is deeply saturated from weeks of repeated rain — climbing now risks permanent hold breakage and irreversible damage to routes.
- Surface-dry appearance is misleading: the rock will look climbable long before it is structurally safe, especially in the sheltered sections.
- Bird nesting restrictions may be active in June — verify with the BMC RAD before any visit.
Reasoning
The rock has been subjected to repeated wetting events over the past two weeks (8.5mm on June 1st, 12mm on June 2nd, 6.7mm on June 3rd, 8.1mm on June 4th, then further rain on June 6th, 8th, 9th, 10th, and 11th), with only a 3-day dry window (June 12–14) before today's renewed precipitation — the internal moisture content will be very high despite any surface drying.
The 3 dry days from June 12–14 brought reasonable wind (20–37 km/h) but the sheltered valley position limits effective airflow at the rock face, humidity remained 70–78%, and the west aspect receives only afternoon sun — wholly insufficient to dry out sandstone saturated by over 35mm of rain in the preceding 10 days.
With repeated saturation cycles over weeks and no extended drying period, the Fell Sandstone will have significant compressive strength reduction (potentially 30%+), making hold breakage a serious risk especially on the iron oxide-cemented features that define the climbing.
Although June is nominally the best season for Northumberland sandstone, this has been an unusually wet spell and temperatures have been cool (averaging only 11°C over the past week), limiting evaporative drying capacity.
Contributing Factors
6
Over 35mm fell between June 1–11 across multiple events with no extended dry window, keeping the porous sandstone internally saturated throughout.
Only 3 consecutive dry days (June 12–14) elapsed before today's rain, far short of the minimum needed to dry deeply saturated Fell Sandstone in a sheltered setting.
The wooded, sheltered valley dramatically reduces effective wind exposure at the rock surface, slowing evaporation compared to open hilltop crags.
Humidity has averaged 77% over the past week, severely limiting evaporative drying potential even during the brief dry window.
Averaging only 11°C over the past week provides limited thermal energy for evaporation, further extending required drying time.
Rain is forecast every day from June 15–20 (totalling ~10mm), meaning no drying window is available for at least the next 5 days.
Recommendations
3
- Do not climb at Back Bowden Doors until a sustained dry period of at least 4–5 consecutive dry days with low humidity follows the current wet spell.
- Monitor the forecast beyond June 20th — the first realistic climbing window would be after several dry days following the last forecast rain.
- If visiting the area, consider non-porous alternatives such as the Whin Sill crags (e.g. Crag Lough, Peel Crag) which are far more tolerant of damp conditions.

Despite three dry days since the last rain on June 11 (6.5mm), the preceding two weeks saw over 50mm of cumulative rainfall with only brief dry spells, leaving the porous Fell Sandstone likely still holding significant internal moisture. The sheltered valley position, moderate humidity (~77%), and cool temperatures (~11°C average) have severely limited drying potential, and further rain is forecast from tomorrow onwards.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley and wooded setting at Back Bowden Doors dramatically slows drying compared to the exposed hilltop of Bowden Doors proper — expect conditions here to lag by a day or more.
- The powerful roof problems and overhangs can weep from above for days after rain as water percolates through the sandstone from the top of the crag.
- The prolonged wet period from late May through early June (52.8mm in 28 days with rain on 10 of the last 14 days) means the sandstone has had almost no opportunity to dry internally despite brief surface drying.
- Seasonal bird nesting restrictions may be in effect — check the BMC RAD before visiting.
Warnings
3
- The rock surface may appear dry while the interior remains dangerously saturated — do not rely on visual or touch checks alone given the cumulative wetting history.
- Roof problems and overhangs may still be weeping from above even if the main face looks dry.
- Climbing on internally damp Fell Sandstone risks permanent, irreversible damage to the SSSI-designated rock and its iron oxide holds.
Reasoning
The rock has received 14.1mm in the last 7 days across multiple rain events (June 8, 9, 10, 11), with only 3 dry days since, and the cumulative 52.8mm over 28 days means the sandstone is almost certainly still holding substantial internal moisture despite any surface drying.
Three dry days with moderate SW/W winds but cool temperatures (~13–17°C) and humidity averaging 77% in a sheltered, partly wooded west-facing valley provide only limited drying — far short of what is needed to clear weeks of accumulated moisture from porous Fell Sandstone.
With repeated wetting cycles over the past two weeks and inadequate drying intervals, internal moisture levels are likely elevated, increasing the risk of hold breakage and grain loosening on the iron oxide-cemented holds that define the climbing here.
Early June should offer reasonable drying conditions, but the unseasonably wet and cool weather pattern has negated the seasonal advantage, and the forecast shows more rain arriving tomorrow through June 18.
Contributing Factors
6
52.8mm over 28 days with rain on at least 10 of the last 14 days has kept the porous sandstone in a near-continuously saturated state with no adequate drying window.
Three consecutive dry days since the last significant rain (6.5mm on June 11) is insufficient to dry deeply saturated Fell Sandstone, especially given the repeated prior wetting.
The sheltered, partly wooded valley setting significantly reduces wind exposure and sun hours, slowing evaporation compared to open hilltop crags.
Average temperature of 11.4°C and 77% humidity over the last week severely limit evaporation rates from the rock surface.
Winds of 20–39 km/h in recent days provide some drying assistance, though the sheltered position reduces effective airflow at the crag face.
Light rain is forecast for June 15 (0.8mm) with heavier rain on June 16 (5.2mm) and further showers on June 17–18, preventing any meaningful drying window from developing.
Recommendations
3
- Do not climb today — the rock has had insufficient drying time after a prolonged wet period, and the sheltered setting means internal moisture is very likely still present.
- Wait for a sustained dry spell of at least 4–5 days with lower humidity before considering a visit, given the cumulative saturation from weeks of repeated rain.
- Check the BMC RAD for any active bird nesting restrictions before planning a trip.

Despite two dry days with good wind, the sheltered valley position of Back Bowden Doors means it is unlikely to have fully dried after 6.5mm of rain on June 11 and a very wet preceding fortnight (52.8mm in 28 days). The porous Fell Sandstone will have been deeply saturated, and the sheltered, wooded setting significantly retards drying — the responsible choice is to wait.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley and wooded surroundings dramatically slow drying compared to the exposed hilltop of Bowden Doors proper — expect conditions here to lag by 1–2 days or more.
- The powerful roof problems are known to weep from above after rain, and with the cumulative saturation from the past two weeks, seepage lines may persist for several more days.
- West-facing aspect receives only afternoon and evening sun, providing limited solar drying — particularly problematic given the cool temperatures (averaging only ~12°C recently).
- Seasonal bird nesting restrictions may be in effect during June — check the BMC RAD for current closures before visiting.
Warnings
2
- Do not climb on the roof problems or any routes showing seepage — weeping from above after prolonged rain can persist for days in this sheltered setting.
- Surface-dry rock does not mean safe rock: after two weeks of repeated saturation, internal moisture may still reduce sandstone strength by 30%+ even when the surface appears climbable.
Reasoning
The crag received 6.5mm on June 11 following a prolonged wet spell (over 35mm from June 1–11), meaning the sandstone was deeply and repeatedly saturated with only brief intermittent dry spells insufficient for full internal drying.
Two full dry days (June 12–13) with strong westerly winds (30–36 km/h) have aided surface drying, but the sheltered valley position limits effective wind exposure and the cool temperatures (~14–18°C) and moderate humidity (~70%) mean internal moisture will persist — 48 hours is marginal even for exposed crags after this level of saturation.
The cumulative saturation over the past fortnight means internal pore water is likely still well above the threshold for significant strength reduction, creating a real risk of hold breakage on the iron oxide features climbers depend on.
Early June conditions are generally favourable for drying but this has been an unusually wet spell; the cool northerly influence forecast for June 14–15 will further slow any remaining drying.
Contributing Factors
6
Over 35mm fell between June 1–11 in repeated pulses, deeply saturating the porous sandstone with no adequate drying window between events.
Two days of drying after prolonged saturation is insufficient for a sheltered Fell Sandstone crag, where guidelines recommend 48–72+ hours after heavy rain at exposed sites.
36 km/h westerly wind today directly hits the west-facing crag and accelerates surface evaporation, though the sheltered valley reduces effective wind speed at the rock face.
The valley and woodland shelter significantly reduce wind exposure and air circulation at the rock surface, trapping humid air and prolonging drying times.
Average humidity of 70–71% over the last two dry days limits evaporation rate compared to the 50–60% range ideal for rapid drying.
Temperatures averaging only ~12°C over the past week slow evaporation from the rock's interior pore network.
Recommendations
3
- Wait at least one to two more fully dry days before visiting — if June 14 and 15 remain dry as forecast, conditions may improve to assessable by June 15 or 16.
- If visiting, perform the ground-moisture test at the crag base: if soil or leaf litter is damp, the rock above is almost certainly still wet internally.
- Check the BMC RAD for any active bird nesting restrictions at Back Bowden Doors before planning a visit in June.

Back Bowden Doors received 6.5mm of rain yesterday (June 11) and has had only one dry day since, following a very wet period that deposited over 50mm in the last four weeks. Despite today's westerly wind and lower humidity, the sheltered valley position and porous Fell Sandstone mean the rock is almost certainly still holding significant internal moisture — climbing today risks both hold breakage and permanent crag damage.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley setting and partial tree cover dramatically slow drying compared to nearby Bowden Doors proper — expect at least an extra day of drying time beyond normal guidelines.
- The powerful roof problems and overhanging features can weep from seepage above for days after heavy rain, even when vertical faces appear surface-dry.
- Cumulative rainfall of ~53mm over the past 28 days means the sandstone has had very little opportunity to fully dry out internally — prolonged saturation weakens the rock beyond what a single drying window can fix.
- Seasonal bird nesting restrictions may be in effect through June — check BMC RAD before visiting.
Warnings
3
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing on damp rock risks permanent hold breakage and irreversible crag damage.
- The rock surface may appear dry while the interior remains saturated; do not rely on visual assessment alone after this volume of recent rain.
- Roof problems and overhangs may be actively weeping from seepage above — inspect carefully even if vertical faces seem dry.
Reasoning
With 6.5mm falling yesterday, 2.0mm the day before, and over 35mm in the preceding ten days, the rock is almost certainly saturated internally despite one dry day with moderate wind.
Today's westerly wind at 28 km/h and 70% humidity provide reasonable surface drying, but the sheltered valley position limits airflow at the crag face, and the west aspect receives only evening sun — one day is far too short to dry porous Fell Sandstone after this volume of recent rain.
Internal moisture levels are likely well above the critical threshold where significant compressive strength loss occurs; climbing risks grain loosening and hold breakage on the iron oxide features that characterise the routes.
Early June conditions are improving but the recent prolonged wet spell and moderate temperatures (~11–15°C) have prevented adequate drying; the crag needs a sustained dry spell of at least 3–4 days given its sheltered aspect.
Contributing Factors
6
6.5mm fell yesterday following a prolonged wet period totalling ~53mm over 28 days, keeping the porous sandstone deeply saturated.
A single dry day is far below the minimum 48–72 hours needed after heavy rain on Fell Sandstone, especially at a sheltered crag.
The valley setting and tree cover significantly reduce airflow at the rock face, slowing evaporation despite moderate winds recorded at the weather station.
Westerly wind at 28 km/h and humidity dropping to 70% are helping surface drying, though this is insufficient to address deep internal moisture.
The rock has been repeatedly wetted over weeks with minimal drying windows, meaning internal moisture levels are likely very high and will take longer than usual to dissipate.
The west-facing crag only receives afternoon and evening sun, reducing solar-driven evaporation compared to a south-facing venue.
Recommendations
3
- Do not climb today — wait for at least 2–3 consecutive dry days with low humidity before visiting.
- Check the BMC RAD for any active bird nesting restrictions before planning a trip.
- When conditions improve, test the base of the crag: if the ground is at all damp rather than sandy-dry, the rock is still too wet internally.

Back Bowden Doors is currently receiving heavy rain today (8.9mm) on top of a very wet recent period — 17mm in the last 7 days and over 55mm in the last 28 days. The sheltered valley position and porous Fell Sandstone will require at least 72 hours of dry weather before conditions could be considered, and the rock is almost certainly saturated internally.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley position and partial woodland cover significantly reduce airflow at rock level, meaning drying times here are substantially longer than at the nearby exposed hilltop of Bowden Doors proper.
- The powerful roof problems and overhanging sections are known to weep from above after rain, and with the cumulative saturation from recent weeks these seepage lines will persist for days.
- The west-facing aspect receives only afternoon/evening sun, which combined with the sheltered setting means the crag misses the strongest drying period of the day.
- Bird nesting restrictions may apply in late spring/early summer — check the BMC RAD for current seasonal access notes before visiting.
Warnings
2
- The Fell Sandstone is almost certainly saturated internally — do not climb even if the surface appears to dry; internal moisture causes catastrophic hold breakage.
- Roof problems and overhanging sections will weep from seepage lines for days after this prolonged wet period — avoid these areas longest.
Reasoning
The rock is almost certainly saturated throughout given 8.9mm of rain today, multiple rain events over the past 10 days totalling over 35mm, and consistently high humidity (78% average over the last week) — internal moisture levels will be very high.
Drying has been negligible because there have been no consecutive dry days in over a week; the sheltered valley position blocks wind at crag level despite moderate regional winds, and the west aspect limits direct sun exposure to late afternoon only.
At current saturation levels the Fell Sandstone will have lost 30%+ of its compressive strength, making hold breakage and grain loosening a serious risk — climbing now would cause permanent damage to the iron-oxide holds.
Early June should offer reasonable drying potential, but this has been an unusually wet spell; temperatures are moderate (11–15°C) but not warm enough to drive rapid evaporation in a sheltered, humid setting.
Contributing Factors
7
8.9mm of rain falling mostly midday today ensures the rock surface and interior are fully wetted.
Over 35mm of rain in the last 10 days with no consecutive dry days means the sandstone has had no opportunity to begin meaningful internal drying.
55.2mm over the last 28 days represents sustained wetting that will have driven moisture deep into the porous sandstone.
The wooded, sheltered valley dramatically reduces effective wind at the rock face, severely hampering evaporative drying.
Average humidity of 78% over the last week and 87% today greatly reduces the atmosphere's capacity to draw moisture from the rock.
Temperatures of 13–17°C provide some evaporative potential but are not warm enough to compensate for sheltered position and high humidity.
The forecast shows mostly dry conditions from June 12 onward with lower humidity (65–71%) and moderate wind, which will begin the drying process.
Recommendations
3
- Do not climb at Back Bowden Doors today or for at least the next 2–3 days; the rock is saturated and any climbing would risk permanent hold damage.
- Monitor conditions closely from June 14 onward — if the dry spell holds, perform a careful visual and tactile assessment of the rock before climbing, paying particular attention to seepage lines above the roof problems.
- Consider visiting the more exposed and faster-drying Bowden Doors proper first, as it will reach climbable condition sooner than the sheltered Back Bowden Doors.

Back Bowden Doors is currently unsafe to climb. The crag has received over 35mm of rain in the past 9 days, with further rain falling today and forecast through June 11th; the sheltered valley position and high humidity mean the porous Fell Sandstone will remain saturated internally for days yet.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley setting and wooded surroundings trap moisture and still air, meaning Back Bowden Doors dries significantly slower than the exposed hilltop at Bowden Doors proper — add at least an extra day to any drying estimate.
- The powerful roof problems and overhanging sections are known to weep from drainage above after rain, and the cumulative 35mm+ over the past 9 days will keep seepage lines active for several days after rain stops.
- West-facing aspect receives only afternoon/evening sun, which combined with the sheltered position provides limited solar drying — wind from the SW/W forecast later this week will help but cannot compensate for ongoing rain.
- Bird nesting restrictions may be in effect during June — check the BMC RAD for current seasonal closures before visiting.
Warnings
2
- Climbing on saturated Fell Sandstone causes permanent, irreversible damage to holds and routes — the rock may appear surface-dry while remaining dangerously weak internally.
- Over 35mm of rain in the past 9 days means internal saturation is well above the critical threshold for structural damage; do not be tempted by any brief dry spells today or tomorrow.
Reasoning
The crag has received approximately 35.3mm of rain since June 1st (including 5.1mm today), with high ambient humidity averaging 80% over the past week — the rock is almost certainly saturated throughout, well above the critical 60% pore saturation threshold.
Despite some SW wind, the sheltered valley position negates much of its drying benefit, and with rain continuing today and forecast through June 11th, no meaningful drying period has begun or will begin until June 12th at the earliest.
At current saturation levels the Fell Sandstone will have lost 30%+ of its compressive strength, making hold breakage on the iron oxide features a serious risk — climbing now would cause permanent, irreversible damage to routes.
Early June should offer improving conditions, but this prolonged wet spell with moderate temperatures (12–15°C) and high humidity is preventing the seasonal drying advantage from materialising.
Contributing Factors
6
Over 35mm has fallen in the past 9 days across multiple events (8.5mm, 12.0mm, 6.7mm, 8.1mm, 2.1mm, 5.1mm today), keeping the rock continuously saturated with no meaningful drying window.
Today's hourly forecast shows scattered showers totalling ~5mm, with a further 5.7mm forecast for June 10th and 3mm on June 11th, resetting any drying progress.
Humidity has averaged around 80% over the past week and remains elevated at 79–89% today, severely limiting evaporative drying even when rain pauses.
The wooded, sheltered valley traps moist air and blocks wind, dramatically slowing drying compared to exposed crags — this is the slowest-drying Fell Sandstone venue in the area.
Winds of 18–33 km/h from the SW/W are forecast from June 12th onwards, which will aid surface drying once the rain stops, though the sheltered position reduces their effectiveness.
Temperatures of 13–15°C with lows around 8–9°C are below late-spring averages for Northumberland, slowing evaporation rates.
Recommendations
3
- Do not climb at Back Bowden Doors until at least 48–72 hours of dry weather have elapsed after June 11th — the earliest realistic window is June 14th, and even then assess conditions carefully on arrival.
- Before climbing, check that the ground at the base of the crag is sandy-dry and that no weeping is visible on the roof problems — if either is damp, walk away.
- Check the BMC RAD for any active bird nesting restrictions before visiting, as June is peak nesting season.

Back Bowden Doors has received over 30mm of rain in the last 7 days across multiple events, with the most recent rain falling this morning (3.1mm today including heavy bursts at 05:00–06:00). The sheltered valley position, high recent humidity (~80% average), and porous Fell Sandstone mean the rock will be thoroughly saturated internally — climbing today or in the immediate future would risk permanent damage to holds and routes.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley position and wooded section dramatically slow drying compared to the exposed hilltop at Bowden Doors proper — expect at least an extra day of drying time beyond normal guidelines.
- The powerful roof problems are known to weep from above after rain, and the cumulative 30mm+ over the past week means seepage through the cap rock is likely to persist for several days.
- West-facing aspect receives only afternoon/evening sun, which combined with the sheltered setting means solar drying is limited to a few hours per day at best.
- Seasonal bird nesting restrictions may be in effect during June — check the BMC RAD before visiting even when conditions eventually dry.
Warnings
3
- Fell Sandstone loses up to 50% of its compressive strength when wet — climbing now risks permanent hold breakage and irreversible route damage.
- The rock surface may appear dry in afternoon sun while remaining deeply saturated internally; do not be deceived by surface appearance after this much rain.
- Further rain is forecast for June 9–10, meaning safe conditions are unlikely before at least June 13–14 at the earliest.
Reasoning
With 30.4mm in the last 7 days across four separate rain events (June 1–4) plus additional rain on June 6 and today June 8, the porous Fell Sandstone will be deeply saturated internally well beyond the critical 1% threshold where significant weakening begins.
The only meaningful dry window was June 5 and June 7 (two isolated days), which is wholly insufficient to dry sandstone after 35mm+ of cumulative rain — especially in a sheltered valley with 80% average humidity and limited direct sun on the west-facing aspect.
At current saturation levels, compressive strength is likely reduced by 30%+ (Bell 1978), and the iron-oxide cemented small holds that characterise Fell Sandstone are at serious risk of breakage under load.
Early June temperatures (12–15°C) are moderate and would normally aid drying, but the persistent high humidity and repeated rain events have prevented any meaningful drying cycle from completing.
Contributing Factors

Over 30mm in the past 7 days across multiple events (June 1–4, 6, and 8) has deeply saturated the porous sandstone with no adequate drying window between events.
3.1mm fell this morning with the heaviest bursts (1.5mm and 1.1mm) between 05:00–06:00, resetting any minor surface drying that may have occurred.
The sheltered, partly wooded setting significantly retards airflow and evaporation compared to exposed hilltop crags, extending drying times substantially.
Average humidity of 80% over the last 7 days severely limits evaporative drying, and today's early morning humidity reached 98%.
Wind speeds of 20–27 km/h from the SW/W would normally aid drying, but the sheltered valley position limits how much wind reaches the rock face.
5.9mm forecast for June 9 and 4.8mm for June 10 will further saturate the rock and restart the drying clock entirely.
Recommendations
3
- Do not climb at Back Bowden Doors today or for several days — the rock is saturated from repeated rain events and needs an extended dry spell to recover.
- Monitor conditions after June 11 when a potential dry window begins, but expect at least 48–72 hours of dry weather from the last rain before considering a visit.
- Check the BMC RAD for any active bird nesting restrictions before planning a visit, as these commonly apply at Northumberland sandstone crags through June.

Back Bowden Doors has received nearly 36mm of rain over the past week (June 1–4), with the last significant rainfall just 3 days ago and a trace amount yesterday; combined with the sheltered valley position, high humidity averaging 83%, and only one full dry day, the porous Fell Sandstone will still be saturated internally. The forecast shows further rain arriving tomorrow and continuing through the week, making any meaningful drying impossible.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered valley position and wooded surroundings dramatically reduce airflow and sun exposure, meaning drying here takes significantly longer than at the nearby exposed hilltop of Bowden Doors proper.
- The powerful roof problems and overhanging sections are known to weep from above after rain — with 36mm in the past week, seepage lines will be actively dripping.
- The west-facing aspect only receives afternoon/evening sun, limiting solar drying to a narrow daily window that is insufficient to overcome the current moisture loading.
- Bird nesting restrictions may apply at this time of year (June) — climbers should check with the BMC RAD for any current seasonal closures before planning a visit.
Warnings
3
- Climbing on this saturated Fell Sandstone risks permanent hold breakage and irreversible damage to routes at an SSSI-designated site.
- The rock surface may begin to appear dry before the interior has dried — do not be misled by surface appearance at this crag.
- Roof problems and overhangs will be actively weeping from seepage; falling on wet holds at height poses a serious injury risk.
Reasoning
With 35.8mm of rain in the past 7 days — including 8.5mm, 12mm, 6.7mm, and 8.1mm on consecutive days June 1–4 — plus 0.5mm on June 6, the rock will be deeply saturated internally despite one dry day today.
Only one full dry day has elapsed since the last trace rain (0.5mm on June 6), and only three days since heavy rain (8.1mm on June 4); the sheltered, wooded valley position with 83% average humidity and limited wind penetration means drying is extremely slow — a minimum of 72+ hours of dry weather would be needed even in good conditions, and far longer given this site's characteristics.
At current saturation levels the Fell Sandstone will have lost 10–50% of its compressive strength; climbing now risks hold breakage and permanent erosion damage to this SSSI-designated crag.
Early June should offer reasonable drying potential, but the current spell of high humidity (83% average) and cool temperatures (~13°C average) is performing well below seasonal norms, and the incoming forecast rain will reset any drying progress.
Contributing Factors

35.8mm fell in the past 7 days across multiple events (June 1–4 and June 6), deeply saturating the porous sandstone.
Only one full dry day since the last rain, far short of the 72+ hours needed after heavy rain on sheltered porous sandstone.
The wooded, sheltered valley dramatically reduces wind penetration and sun exposure, slowing evaporation well below what open hilltop crags would achieve.
Average humidity of 83% over the past week severely limits net evaporation from the rock surface.
Rain is forecast every day from June 8–12 totalling 17.4mm, preventing any meaningful drying window from developing.
27 km/h SW wind today provides some surface drying benefit, but penetration into the sheltered valley is limited and one day is insufficient.

- Do not climb at Back Bowden Doors until there have been at least 3–4 consecutive dry days with humidity below 70% — current conditions and the forecast make this unlikely before mid-June at the earliest.
- Check the BMC RAD for any active bird nesting restrictions before planning a future visit, as June is peak nesting season.
- If you are in the area and keen to climb, consider non-porous alternatives such as whinstone crags (e.g. the Great Whin Sill venues) which are less affected by moisture.
Do Not Climb

Back Bowden Doors has received nearly 38mm of rain over the past week, with the last significant rainfall (8.1mm) only two days ago and further light rain today. The sheltered valley position, high humidity (~83% average), and porous Fell Sandstone mean the rock is almost certainly still saturated internally, and the forecast promises no meaningful drying window for at least five more days.
Based on weather conditions only — does not cover bird nesting restrictions or other access issues.
- The sheltered, partially wooded valley position significantly retards drying compared to the exposed hilltop at Bowden Doors proper — expect drying to take at least 50% longer than guidelines suggest.
- The powerful roof problems and overhanging features are known to weep from above after rain, and with 37.9mm in the past week, seepage through the caprock is likely still active.
- West-facing aspect receives only afternoon/evening sun, which combined with the sheltered setting provides limited solar drying — especially problematic during the current run of cool, humid weather.
- Bird nesting restrictions may be in effect during June — check the BMC RAD for current seasonal closures before planning a visit.
Warnings
2
- Climbing on this saturated Fell Sandstone risks permanent hold breakage and irreversible damage to routes — the rock may look surface-dry in places but internal saturation is near-certain.
- The roof problems are likely actively weeping from caprock seepage and should be avoided entirely.
Reasoning
With 37.9mm of rain in the past seven days — including 8.1mm on June 4th and 1.0mm today — and average humidity of 83%, the rock is almost certainly saturated well beyond the critical 1% threshold at which significant weakening begins.
Only one full dry day (June 5th) has elapsed since the last heavy rain, and today brought further light rain; the sheltered valley position and high humidity severely limit evaporation, meaning even surface drying has barely begun.
At current moisture levels, Fell Sandstone strength is likely reduced by 30–50%, creating serious risk of hold breakage on the iron-oxide-cemented features that define the climbing here.
Early June temperatures (averaging ~13°C) are moderate but the persistent high humidity and frequent rainfall are preventing the sustained dry spell needed for this sheltered venue to come into condition.
Contributing Factors

37.9mm over the past seven days, with significant events on June 1st (8.5mm), 2nd (12.0mm), 3rd (6.7mm), and 4th (8.1mm), has thoroughly saturated the porous sandstone.
Only one dry day (June 5th) since the last heavy rain, and today has brought a further 1.0mm — far short of the 48–72+ hours needed after heavy rain even at an exposed crag.
Average humidity of 83% over the past week severely limits evaporative drying, especially in a sheltered valley where air movement at the rock face is restricted.
The wooded, sheltered setting means wind barely reaches the rock face, removing the single most effective mechanism for accelerating drying on a west-facing crag.
Regional wind speeds of 20–27 km/h are reasonable but the sheltered valley position means little of this reaches the crag face.
The forecast shows further rain on four of the next five days (totalling ~34mm), meaning no meaningful drying window is available.
Recommendations
3
- Do not climb at Back Bowden Doors until at least 72 hours of dry weather with humidity below 70% have elapsed — given the forecast, this is unlikely before mid-June at the earliest.
- Check the BMC RAD for any active bird nesting restrictions before planning a visit, as June falls within the typical nesting season.
- If you are keen to climb this weekend, consider a non-porous alternative such as a whinstone or limestone crag in the region where wet-rock damage is not a concern.
